Answer:

Step-by-step explanation:

5(d - 68) = 85

Use distributive property

5*d - 68*5 = 85

5d - 340 = 85

Add 340to both sides

5d = 85 + 340

5d = 425

Divide both side by 5

d = 425/5

d = 85

The center of a circle is located at (2, 3) and has a radius of 6 units. Which equation represents this circle?
Helen [10]

By using the general equation for a circle, we will see that the correct option is:

(x - 2)^2 + (y - 3)^2 = 36

<h3>How to find the equation for a circle?</h3>

The general equation for a circle centered at the point (a, b) of radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

In this case, the center is (2, 3) and the radius is R = 6 units, replacing that in the above equation we get:

(x - 2)^2 + (y - 3)^2 = 6^2

(x - 2)^2 + (y - 3)^2 = 36

So the correct option is B.

Prove algebraically that each expression has the same value by evaluating each expression for y=5:
Illusion [34]

Answer:

See explanation

Step-by-step explanation:

Given two expressions

7(3y-5)-2(10+4y)

and

13y-55

Substitute y = 5 into each expression:

1.

7(3y-5)-2(10+4y)\\ \\=7(3\cdot 5-5)-2(10+4\cdot 5)\\ \\=7\cdot (15-5)-2\cdot (10+20)\\ \\=7\cdot 10-2\cdot 30\\ \\=70-60\\ \\=10

2.

13y-55\\ \\=13\cdot 5-55\\ \\=65-55\\ \\=10

As you can see the results are the same.

Seven less than the product of 8 and a number equals 4
Vlad1618 [11]

Answer:

11/8 or 1 3/8 or 1.375

Step-by-step explanation:

From the information given by the question, we can form an equation:

Let us call the number 'n'

8 × n - 7 = 4

We then move the 7 to the other side, changing it from minus to plus:

8 × n = 4 + 7

So,

8 × n = 11

We divide both sides by 8, to leave n on one side of the equation.

n = 11/8

Therefore, n = 11/8 or 1 3/8 or 1.375
